I've fixed that, and made the changes above.  However, I think $(libdir)
and $(bindir) should be configurable as options to ./setup configure
(weren't we going to do that at one stage?).

The story is now:

On Windows,

   prefix  | is_excutable = $(ProgramFiles)\$(PackageId)
           | is_library   = $(ProgramFiles)\Haskell\$(PackageId)

   libdir = $(prefix)\$(CompilerId)
   bindir = $(prefix)\bin

On Unix,

   prefix = "/usr/local"
   libdir = $(prefix)/$(PackageId)/$(CompilerId)
   bindir = $(prefix)/bin

This is ok for the default prefix, but not great if you want to set
prefix to /opt/pkg-1.0, for example - that's why we need to be able to
set libdir independently.
